The config files aren't fully compatible and the Linux fc-cache prints
some errors about that but they can be ignored it seems.

The cache files have names ending in -<arch>.cache-<version> where <arch>
is le32d4 on i386 and le64 on amd64 and <version> is 7 on FreeBSD, 3 on
CentOS 6 and 4 on CentOS 7, so a simple link doesn't work.

The commit also doesn't fully solve the problem.  The amd64 package only
generates le64 cache files so running an i386 Linux program may still
create cache files in the user home directory.  This also happens when
users update their fonts because font ports don't run Linux fc-cache on
installation.

The only real solution is to build our own Linux fontconfig package using
devel/linux-*-devtools.
